This study supplements the identification program of a complete sample of sources with CR >= 0.5 cts/s presented previously (Thomas et al. 1998, A&A, 335, 467; available at the HEASARC as the RASSHGSOFT table). Spectroscopic identifications are presented for 70 of 77 sources, 5 sources are identified by other means, and subsidiary information is given for 2 as yet unidentified sources. In practically all cases, a unique optical counterpart exists. As for the brighter fraction of the sample, the largest source classes are Seyfert 1 galaxies, magnetic cataclysmic variables, and hot white dwarfs. In the Galactic Pole caps at |b| > 40 degrees, Seyfert galaxies dominate, whereas at intermediate latitudes galactic objects as magnetic cataclysmic variables and white dwarfs become relatively more frequent.
